Re: [v6ops] Reused deprecated prefix (0200::/7)

[Brian E Carpenter <[e-mail]>]

To which draft? I'm not aware of an Yggdrasil draft.

Note that they use all 121 bits after the /7 prefix, I think for cryptographic reasons. So a ULA prefix wouldn't actually do what they want, as I understand it.

looks as if it is still pre-production code similar in nature to ZeroTier 
or the Slack nebula, the former of which is able to leverage both rfc4193 
and 6plane as its addressing schema. While no one can expect to control what is used on private networks and projects, I don't see this particular 
issue as a show stopper for this particular draft, assuming this is in use as a private addressing schema and not as rfc4548. Based on the site, that appears to be the case:

which simply never materialised 14 years later. It was decided to use this range instead of fc00::/7 (which is more typically allocated to private 
networks) in order to prevent conflicts with existing ULA ranges./
